2005 jeep grand cherokee oil pressure sensor location

My instrument panel oil pressure indicator comes on when rpm's drop below 1k and stopped with a ding. I just had the oil changed within six weeks. Dip stick ok. I suspect a bad sensor. Yes?

Quite possibly. Its one of those things that I wouldn't feel comfortable without having checked the oil pressure with a mechanical gauge before assuming all was well with the sensor.

Do you have any engine noise? noisy lifters, a knock?

Engine is running perfectly. No unusual noises or vibrations or hesitations or variations in idle. Running smooth as silk, as they say all across the rpm spectrum.

I am assuming if you pull the connector on the oil pressure sender you will see that the sender is leaking. I personally still like to verify oil pressure (makes me feel better). BUT, with hydraulic lifters, they get pretty noisy with no oil pressure. It is likely a sender issue.

I forgot to add the oil level is right on the money. It does not mark it's territory. Where is the sensor located? Is it easy to get too? I have a FSM but I can't locate where the sender is in the manual.

The oil pressure sensor sits just below the oil filter.
